VEHICLE-WHEEL.

Patented Sept. 28, 1909.

Application filed January 21, 1908 Serial No. 411,890.

Be it known that I, DAVID I. PAISNEIna citizen of the United States, anda resident of Chelsea, in the county of Sufiolk and 9 StateofMassachusetts, have invented a new and Improved Vehicle-Wheel, of whichthe following is a full, clear, and exact descripion.

My invention relates tovehicle wheels, and has for its principal objectto provide a wheel which will have all the resiliency of a wheel with a;pneumatic tire, without-the disadvantages.

Another object is to provide a vehicle wheel with two rims which areseparated and held normally in their relative positions by sprin andguides, which will not only rmit t e outer rim to move toward the innerr 1m and thus furnish the resiliency desired, but will also permit theouter rim to rotate sli htly, relatively to the inner rim and thuslrnish additional resiliency.

In -the drawings, I have drawn one embodiment of my invention which Iwill now describe, but I do not limit myself thereto as I considermyself entitled to all forms and embodiments of the invention which mayfall within the see e of the appended claims.

Reference is to be had to the accompanyr ing drawings formin a part ofthis specification, in which simi ar characters ofrefe'rence indicatecorresponding parts in all the figures.

Figure 1 is a side, Sectional elevation showing the inner. and outerrims and the position of the springs therebetween. Fig. 2 is an enlargedfragmentar sectional view showing the method 0 assembling the s rings,and the inner and outer rims, and t e devices by which they are secured,the view bein taken of the fragment between the lines -A and B-B inFig. 1. Fig. 3 is an enlar ed sectional view of the shields and the balIbearings which prevent friction between the shields and the outer rim,and Fig. 4 is a view of the ball bearing on the shield on line 4-4 inFig. 3.

By referringto the drawings, it will be seen that 1 is the hub and 2 arethe spokes, which are rigidly secured to the inner rim 3. Between theinner rim 3 and the outer rim 4 are disposed a plurality of doublehelical springs 5., which are firmly secured to the outer rim and whichpress against the inner rim. The inner terminals of the springs passthrough elongated eyes 6 and are held by screws 7 which fit threads inthe outer sides of the said elongated eyes. By this construction, theinner and outer rims may be quickly separated, when it is necessary tomake repairs.

Referring more particularly to ,Fig. 2, it will be seen that the twoterminals of each spring 5 are oppositely disposed in the elongated eyes6 on the inner rim 3, and that the spring is wound in oppositedirections with the central portion 8 in the form of ae11 o'p which liesagainst the outer rim 4; The helical springs 5 are held in place by bars13 which are secured to bearings 14 which are made fast to the outer rim4. 7

As will be Seen, the spring is so adjusted that the outer rim may moveinwardly, or it may rotate slightly around the inner rim 3 when the roadis uneven or when an obstruction is encountered. This will give all thelife to the wheels which is necessary 'to pre-. vent shocks and jars tothe car or carriage on which the wheels may be used. In order to keepdust from collecting between the two rims and also to prevent the outerrim from getting out of place by lateral strains, I provide annularshields 9, which are secured by bolts 10 to the inner rim 3 of thewheel. I also use tubes 11, which are disposed between the shields 9 tokeep them in place, the tubes and shields being held in their normalpositions by bolts 12 passih-"g through the shields and the tubes. Thesetubes 11 and bolts 12 are disposed nearer to the outer rim 4 than to theinner rim 3. The outer ends of the shields 9 act as guides and have ballbearings therein which prevent friction between the outer rim 4 and theshields 9, These ball bearings 15 are preferably fitted in openings inthe shields, there being projections in the openings which arefrusto-conical in shape, the apexes being cut off and made concave andthe walls being threaded to enable the nuts 16 to be screwed down. Theinner portion of the nuts is hollowed and rounded from the inside, sothat the openings will register with the concave portions 17 formed atthe apex of the cone. The ball 20 is held in this bearing formed by thenut 16 and the concave portion 17' of the cbnes and projects slightlybeyond the nut, keeping the nuts or shields from coming into contactwith the outer rim 4:.

A dust guard 18 maybe screwed on the sufiicient in most'cases to meetthe requirements.

The tire 19, which is solid rubber, is secured to the outer rim 4.

By this improvement, a durable wheel and tire are provided which willprevent shocks and furnish all the desired resiliency when travelingover good or bad roads. It is also .possible to take the wheel apartquickly if,

for any reason, the parts need to be replaced.

Having thus described my invention, I claim as new and desire to secureby Letters Patent.

1. In a vehicle wheel, outer and inner rims, helical springs havingterminals disposed tangentially with reference to one of the rims andwhich are secured thereto, bars fixed to one of the rims, the said barsbeing disposed in the coils of the springs respectively to hold them inposition, the diameters of the said bars being considerably less thanthe inner diameters of the coils of the springs, and members of thesprings respectively which press against but are not secured to theother rim.

2. In a vehicle wheel, outer and inner rims,

helical springs having terminals disposed tangentially with reference toone of the rims and which are secured thereto, bars fixed to one of the,rims, the said bars being disposed in the coils of the springsrespectively to hold them in position, the diameters of the said barsbeing considerably less than the inner diameters of thecoils of thesprings, members of the springs respectively which press against but arenot secured to the other rim, and a guide which is secured to oneof therims and which prevents the lateral displacement of the other rim.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
